Abstract (en)
[origin: WO9811733A1] A television system utilizes a common signal processing unit (e.g., a common chrominance demodulator) for processing a combined video signal suitable for coupling to a display device for producing an image having a portion attributable to a main video signal and a portion attributable to an auxiliary video signal. If the common signal processing unit relies upon the color information (e.g., color burst) contained in the main video signal, and the main signal is either non-existent or lacking such color information, then a substitute color information signal will be generated so that the combined video signal may be processed to produce a color auxiliary image, and a monochrome (or non-existent) main image.
